If your child has food poisoning, please tell me what foods should be avoided in the first place and can I continue breastfeeding? I didn't understand what the doctor said about milk, he quickly mentioned that it shouldn't be consumed and left for an emergency call. I don't understand anything about what food is safe or not. When we got home, I wonder if I can still breastfeed or not and which foods are safe? Help anyone who has faced this situation.
